It's always worth looking around the Magento community/forums to see if people have had any issues upgrading to any of those versions, and if there have been issues it prepares you to apply whatever fixes are needed.

Apart from that I'm set up my development environment and run the upgrade straight to 2.1.7 and see what happens. If all goes well you can then deploy to your live server.
